Hey there michaelaromanno,

Thank you for reaching out to us on the forums in regards to this issue. That is strange that the console is turning on at night on you. Do you know if you have your console power settings setup to Energy Saving or Instant on?

About energy-saving and instant-on power modes

I would advise attempting to
Physically Power Cycle your Xbox One console by holding down the power button for about 10 seconds until the console turns off. If this is the Original Xbox One unplug the power supply unit from the wall outlet, the back of the console, and then from the
power supply unit itself. After the indicator light on the power supply unit is completely turned off plug everything back in. Hopefully draining the power supply unit helps resolve this issue.

Give this a try and let us know if it has helped.

Got pets? My cats turn on my Xbox all the time!
